applieation `filed Apri1'.29, 1916,` serial Nt. 94,373.

To all whom t may concern: i

citizen of `the United ,States,residing' at Pittsburgh, i'n-the cunty of Allegheny and State of Pennsylvania, have `invented certain new and useful Improvements in Cushion-Tires, of which the following is a speci-1A ficationa. p l

This invention relates to ycushionftires whiclrobtain resiliency by means other than infiati'onfby air', andmore particularly a tire iof this kind which i'scomposed of an outer' casing andan inclosed resilient core, the latter takingthe .place of the usual infiatlableinner tube of a pneumatic tire.

" The invention has for its object to pro-` vide fa. tire 'of the kind stated which pos-` sesses the resiliency and easy riding qualities of apneumatictire,the core being constructed so that an ample support for the y load placed on the tire is had, together.\vith a wide bearing under Athe entire running area ofthe tire, anda firm support against side thrust.A

f The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may 'be better understood, reference is had to the accompanying drawing, Jforming a part-of In the drawingv Figure l is a side elevation of' a Jfragment of the tire, partly in section;

The vwebs l0 extend fromthe base to the top of' the blocks 9, flush `with theftop, and A adjacent to thelatter they are widened as indicated at 11 to obtaink a'wide surface of".`

shape ot' the corresponding' portions ofthel blocks. The extensions 12 seat on the rim 7 andiprovide a wide base for thewebs, and also lncreasev the thickness .of the base portions of the blocks.

-tends from the base of the'web to the enlarged top portion 1l thereof, leaving the. latter intact. The openings allow the core to stretch easily over therirn7 .when it iS placedinside the casing; 5. v-

The clencher beads 8 are provided with an internal hard rubber reinforcement 14 which extends upward above the clencher flanvfes 15 of the rim 7 so as to revent. rim

cutting. The casing 5 hasinternal shoul ders 1G above the clencher beads, which are engaged by shoulders 17 on Ythe side edges et' the blocks 9. The reinforcement 14 1s continued beyond the clencher-'beads far enough'to reinforce the shoulders 1G also.

Where the tire casing 5, is ,lat on the inside beneath the treadportion, the top of the core in contactlwiththisportion of the casing is alsohunle flat; es shown in Fig.

l'Vhere the casing' is curved as lshown in Fig. 3. the top ot' the, core is lalso made curved, and a hard rubber key 18 extending entirely around the casingis built into the same and tits in a groove in the top et' the core to prevent any tendency jbf the core to turn in thev casing when subjected to a severe side thrust. The core may also be Vulcanized or cemented to the casing 5.

The advantages ot' a core constructed as hereinbefore described are that it gives a Ving ofthe clencher type 'shoulders above its clencher bea solid base under the entire running surface of thetire casing, and the wear is uniform and not in spots'. A firm support against side thrust is provided, and the core can be easily placed inside the tire casing, as the openings in the webs permit vthe core to be easil stretched. Rim cuts are eliminated b `t e hard rubber reinforcement of the c encher beads. The tire will safely carry heavy loads and stand high speeds as well as a pneumatic tire. The base portions of the partitions 9 and the webs 10, where they fit between the cleneher beads 8, are wedgeshaped incross-section- It will therefore be evident that when weight is placed on the tire and the core is compressed, the wedgesliaped base ortions spread, and press the clencher bea s outward against the flanges 15 of the rim 7, so that the tire is firmly clamped to the rim and prevented from creeping.

In order to provide for the ventilation ofV the tire, small holes 19 are made in the wheel felly 6 and throughv the rim 7, in line with the openings 13. These holes keep the tire cool and also prolong the life ofthe rubber. The tire can be applied to the wlieel'in the saine manner as any ordinary clencher `tire and no specially constructed rim is necessary. Y I claim:

1. A cushion-tire comprising an outer cshavin intefnal s and an inclosed resilient core composed of partitions extending across the inside of the casino shoulders which seat on the shoulders of thel casing. I

2. 'A cushion tire comprising an outer casing of the clencher type having its clencher beads provided with an internal reinforcement, and provided with internal shoulders above said beads, the reinforcement being continued beyond the clenclierbeads to reinforce the shoulders, and an inclosed resilient core composed of partitions extending across the inside of the casing, and connecting webs between the partitions joining the saine in a continuous series and in spaced relation, the side edges of the partitions having shoulders which seat on the shoulders of the casing.

3. A cushion tire comprising an outei' casing of the clencher type having its clencher beads provided with an internal reinforce` nient, and provided with internal shoulders above said beads, the reinforcement being continued beyond the clenclier beads to reinforce the shoulders, and an inclosed re,- silient core having side shoulders which seaton the shoulders of the casing.

In testimony whereof I aliix my signature in the presence of two witnesses.
